I'd have to do some testing to be sure. The primary requirements seem
to be:
- #| comments are visible to scheme as a single whitespace
- an error is signaled if a closing is |# not found.
- #| comments can be nested
- R5RS <delimiter> is not extended so tokens, etc. must be separated
from #| comments by a regular R5RS <delimiter>. I presume this
means that you want foo #|bar|#, not foo#|bar|#.
If our #! handling accmodates these requirements, then we're set,
though we might want to specify how #! and #| interact. I'd be likely
to propose:
- a multi-line comment started with #! must end with !#.
- a multi-line comment started with #| must end with |#.
- #! and #| comments may be nested.
and perhaps even
- a #! multi-line comment is only permitted at the start of a scheme
file.
though perhaps there are good reasons not to specify that...
